Reperfusion Injury in Patients With Acute Myocardial Infarction: JACC Scientific Statement.
Journal of the American College of CardiologyDespite impressive improvements in the care of patients with ST-segment elevation myocardial infarction, mortality remains high. Reperfusion is necessary for myocardial salvage, but the abrupt return of flow sets off a cascade of injurious processes that

1999
Abstract Early in the history of cardiac surgery, it was recognized that some patients who underwent technically successful operations suffered from a syndrome of low cardiac output in the early postoperative period. It was also apparent that the perioperative mortality was increased in these patients. Autopsy and clinical studies in the

During cardiac reperfusion after myocardial infarction, the heart is subjected to cascading cycles of ischaemia reperfusion injury (IRI). Patients presenting with this injury succumb to myocardial dysfunction resulting in myocardial cell death, which ...

Reperfusion effect upon ischemic myocardial injury
Experimental and Molecular Pathology, 1979Abstract Coronary artery ligation with or without reperfusion was carried out in Wistar rats to study the role of reperfusion upon ischemic cardiac muscle cell injury by using the fine structural extracellular protein tracer, horseradish peroxidase (HRP).

Peroxynitrite in Myocardial Ischemia-Reperfusion Injury
Heart Failure Reviews, 2002Peroxynitrite is a highly reactive oxidant which is produced during reperfusion of the ischemic heart. The role that this molecule plays in reperfusion injury has been controversial. Many investigations have demonstrated toxic effects of peroxynitrite, whereas others have found it to be protective during reperfusion.

Perioperative myocardial ischemia reperfusion injury
Anesthesiology Clinics of North America, 2003Myocardial I-R injury contributes to adverse cardiovascular outcomes after cardiac surgery. The pathogenesis of I-R injury is complex and involves the activation, coordination, and amplification of several systemic and local proinflammatory pathways (Fig. 4).

Neutrophils and myocardial reperfusion injury
Pharmacology & Therapeutics, 1996Ischaemia induces an acute inflammatory response in myocardial tissue with an early phase of neutrophil accumulation, which is accelerated by reperfusion. In experimental models, interventions that deplete neutrophils or inhibit their function cause a significant reduction in myocardial infarct size. These cells, therefore, may exacerbate tissue injury

Connexin43 and Myocardial Ischemia-Reperfusion Injury
Cardiovascular & Hematological Disorders-Drug Targets, 2018Recently, the treatment and prevention of ischemic cardiomyopathy is one of the emerging research topics in the cardiovascular field. Gap junction is the basic structure of cardiac electrophysiology. Connexin is the basic unit of gap junctions. Connexin43(CX43) is the most abundant member of Cx family in the heart, the normal expression of Cx43 is ...

Myocardial ischemia and reperfusion injury
Cardiovascular Pathology, 2005Myocardial ischemic injury results from severe impairment of coronary blood supply and produces a spectrum of clinical syndromes. As a result of intensive investigation over decades, a detailed understanding is now available of the complexity of the response of the myocardium to an ischemic insult.

Pharmacological therapy for myocardial reperfusion injury
Current Opinion in Pharmacology, 2004In the ischemic myocardium, reperfusion is necessary for the salvage of cells and cardiac function. However, reperfusion itself causes 'reperfusion injury', leading to the damage of myocardial cells. This is reduced by several interventions, as measured by the limitation of infarct size or reduction of arrhythmias.
